Perhaps you have some conflict with existing CSS on your page? It's hard to tell with such little information.

Well the good thing about code is that there is always an explanation for every problem even if it isn't immediately obvious. Can you provide more information, perhaps a link to an example page so people can see the issue? The more information you give the more likely you are to get a response.
